Wind farms (WFs) based on doubly-fed induction generator (DFIG) have become nowadays very popular for the national grid integration option. The reason for this is their ability to support the electric grid with its reactive power. Most of the optimal reactive power (VAR) problems in the past, have dealt with conventional electric grid, and a few with the(More)
Transformer condition monitoring and assessment is crucial as it can be applied to evaluate its maintenance needs. The current trend is to leave critical power transformers in service uninterrupted unless the monitored parameters indicate otherwise. This ensures optimal use of the facility and uninterrupted power supply to consumers. This paper presents the(More)
This paper proposes a novel transmission line fault location scheme, combining stationary wavelet transform (SWT), determinant function feature (DFF), support vector machine (SVM) and support vector regression (SVR). Various types of faults at different locations, fault impedance and fault inception angles on a 400 kV, 361.297 km transmission line are(More)
This study presents a Z Source-T shape - Neurtal point Diode Clamped (NPC) - Multi Level Inverter (MLI) power conversion system (Z-T-NPC-MLI) with the help of New Space Vector PWM (SVPWM) scheme. The proposed impedance source inverter combines the advantages of boosting and conversion of DC to AC power. There are several research papers on T-NPC-MLI(More)
This paper analyses the influence of intermittent wind power generation on the oscillation of a power system considering different load levels. The fluctuation in the eigenvalues and the eigenvectors resulting from intermittent wind power generation are calculated using Monte Carlo simulation with Latin hypercube sampling via modal analysis. An index known(More)
